Looking for Advice on Eczema Supplements

I got maelove skin care samples for my face but their serums are surprisingly effective on the rest of my skin. It's not exactly a supplement, but kinda similar? Also, soaking in chamomile.

Livaplex, probiotics, and fish oil has helped me along with reducing dairy intake as much as possible. I also use cortisone eczema lotion as well

I don’t know of any supplements but prescription steroid cream does the trick!
